DISPENSING AND MEASURING PUMP.

Application filed October 10, 1922. swarm. 593,555.

To all whom) it may concern."

Be it known that I, CHARLES SPAETH, a citizen Cleveland, in the countyof Onyahoga and State of Ohio, have invented certain new and usefulImprovements in a Dispensing and Measuring Pump, of which the followingis a specification.

' This invention relates to a dispensing and measuring pump of the typewhich connects with and is mounted upon the head of a barrel or drum andprovided with an intake pipe extending into'the barrel. These pumps areespecially designed for attachment and use with. the steel barrels ordrums commonly employed to ship and'store oil and grease, and thepresent pump is particularly constructed to permit a quick andconvenient attachment and an operative connection to be made withbarrels and drums of difl'erent sizes and.capacities. In this connectionit should be understood that the barrels and drums in use varyconsiderably in height th and diameter and that to make an operativeconnection capable of permitting all of the contents to be withdrawn itis necessary that the intake end of the pipe for the pump be the extremebottom of thebarrel. It is also advantageous to have the pump bodymounted in a stable manner upon the head of the barrel and not on theintake pipe itself, and to serve such useful ends and purposes I haveconstructed the pump in a particular wa all as hereinafter shown anddescribed an more concisely pointed out in the claims. 1

' In the annexed'drawings, elevation of my improved to a steel barrelofsmall Fig. I is a side pump attached mg in section and part thereofbeing sectional view of the same pump attached to a much larger steelbarrel and sh intake pipe extended its full length and restthe barrel.ig. 3 P p andbarrel, the barrel and the pump intake pipe being brokenaway and foreshorte'ned to rmit the bottom portion of the barrel to eshown on the sheet.

general practice at the present time is to ship and store oil and greasein barrels or drums-made either of wood or metal, but more commonly thelatter, for example a time] 2 such as shown in the drawings." A

of the United States, residing at b size, the barrel owing thefallsbelow the upper end screw-threaded bung opening 3 of standard size isprovided in the head 4 whether the arrel be large or small. Intothisbung opening I screw a tubular fitting or coupling member 5 which isprovided with a reduced screw-threaded extremity 6 for that purpose. Theupper end of coupling member 5 has a relatively long and smooth bore 7and a boss 8 atone side of this bore. The pump base 9 has a shoulderedbottom face 10 adapted to seat upon the flat top ofmemher 5, and also areduced round extension 11 adapted to extend into bore 7 and fit tightlytherein, a set screw 12 being extended through boss 8 to secure theparts together; The chambered middle portion of coupling member 5 isalso provided at one side with a boss 13 adapted to receive a shorthorizontal drain pipe 14 which connects with and supports an overflow ordrain pan 15 directly above the head of the barrel, although thecoupling member may be rotated to place e pan over or beyond the chimeof the barrel if necessary ordesired. Pan 15 has a vertical borderflange 16 and a dished or sloping bottom 17, and thereceptacle orcontainer C which is to receive the oil is adapted upwardly into member5 and connects with thetubula'r extension 11 ofpump base 9.

.' Pipe 20 isrela'tively lon' but of less length than the smaller sizes0 use. An extension sleeve'or tube 21 is therebarrels in generalforeslidablyfitted overthe lower end of pipe 20, and the bottom end ofthe pipe is anged outwardly at 22 to engage an inner shoulder 23 withintheupper end portion of the sleeve or tube 21 so as to secure theseparts together and limit the telescopic movement outwardly of tube 21. Ascrew-threaded ring or gland 24 is sleeved on pipe 20 and screwed intothe upper end of extension tube 21 to compress the packing 25 andmaintain a tight joint around the slidable joint, as otherwise a leak atthis pointmight interfere with the functioning of the pump, especiallywhen the liqiud level in the barrel of extension tube movement thereof.

and exposes the joint to atmospheric pressure, a vent passage being openthrough drain'pipe 14. v The bottomend edge of extension tube 20 isnotched'or scalloped to permit the oil to enter the tube when at restupon the bottom head 26 of the barrel, and if the barrel is a small oneor relatively. short in length the extension tube 21 is telescoped moreor less over pipe 20 as shown in Fig. 1. This setting or relationship ofparts occurs when coupling member 5 is screwed intothe bung-opening orthe pump is en within thejcoupling memteredand secured her, and in thecase of a larger barrel the extension tube 21 adjusts itself or isselfregulable to the'length of the barrel as suming that it is extendedto its limit when just introduced into the barrel. The lower portion ofthe intake pipe is reduced in diameter which provides a stop shoulder2() to limit the upward movement of tube 21, and the flanged end 22limits the downward Tube 21 is also smaller in diameter than thecoupling end 6 of memher 5 to permit it to pass through the opening inthehead of the barrel.

Pump P may be constructed in various wa s, but as shown the base 9thereof has a anged enlargement adapted to seat the cylinder'27, and asuitable valve 28 controls the intake port 29 in this base. piston orplunger 30 is adapted to be reciprocated within the cylinder by means ofa pinion 31 journaled in the dome-shaped head 32 of the pump, and acrank handle 33 is aflixed to the exposed end of the pinion shafti l tto rotate the pinion and operatetheplungerrod 35 which is providedwithirack teeth at one side meshing with the teeth of the pinion.Plunger 34: extends through the top of head 32 and is guided thereby,but inasmuch as the rack teeth permi; escape of the oil" at this pointthe rod tube is screwed is encased by a tube .35 which is closed at itstop bya cap, 37. The bottom end of this into the-upper side of the headand it is of larger diameter internally than the outer diameter of theplunger ro A valved so that a chamber is provided toreceive and holdoi'l during the operation of the; pump;

A goose-neck discharge spout 38 15 connected with one side of head 32,and the discharge end of this s out is located at a higher elevationthan tlie head directl above the drain pan. A screw 39 exten s throughcap 37 to regulate within limits the stroke of the plunger and theamount of liquid to be delivered.

What I claim, is:

1. A dispensing and measuring pump having a tubular base provided with areduced integral extension, a separate hollow coupling member adapted toreceive said extension having an open screw-threaded reduced ortionadapted to be'inse'rted and secure ti htly within an opening in the headof a arrel, a drain pipe connected with the side of said separatecoupling member, a set screw at one side of said coupling member adaptedto engage said pump base extension, a pipe extending through saidcoupling member and connected with said pump base extension, and anextensible inlet tube slidably sleeved upon said pi e adapted to permitsaid pump to be use with barrels of different sizes and capacities.

2. A dispensing and measuring pump having a base provided with a roundsmooth extension, a hollow coupling member having a smooth bore at itsupper end ada ted to receive said extension and a reduce lower end whichis screw-threaded to fit within a screw-threaded opening in a barrel, adrain pan having a lateral drain pipe connected with said hollowcoupling member, an intake pipe for the pump extending through saidcoupling member and connected with said pump base, a tubular extensionslidably mounted upon the lower end of said intake pipe, and spacedstops on said pipe limiting the slidable movement of said tubularextension thereon.

In testimony whereof I afiix my signature hereto.
